摘要
对现有的内燃机车以及加入超大电容后的启动过程进行理论分析,并利用Matlab内的Simulink工具箱中的Simpowersystems模块,对车辆的启动电路和加入电容后的启动电路进行详细的分析和比较,找出了最佳的电容值。Simpowersystems模块可以用于电路、电力电子系统、电机系统、电力传输等过程的仿真,它提供了一种类似电路建模的方式进行模型绘制,在仿真前自动生成用状态方程描述的系统形式,然后在Simulink下进行仿真分析〔1〕。
The course of starting diesel locomotive assisted by big capacitor is studied in this paper. The performanees of the circuit with big capacitor and without big capacitor in start- up are analyzed and compared by using the Simpowersystems model of Simulink toolbox Matalab, and the most optimal capacitance is found out. Model of Simpowersystems can be used in the simulation of circuit, electric power systems, motor vehicle systems and elecltic power transmission. It provides a was similar to circuit modeling to construct models, systems is created before simulation deseribed by state equations. Then, simulation is running under Simulink.
